Windows 2000 Connections
The Windows 2000 computer creates one local area connection for each network adaptor card installed.
Connection Types
- Local area connections - Properties:
- Clients or services used by the connection.
- The protocols bound to each client or service (bindings).
- Provider order specifies the order the bound protocols are used by the client or service when making a connection.
- Dial-up connections
- Direct cable connections between two computers
- Virtual private networking (VPN) connections
- Connections coming into a computer over a port such as over a modem or infared port.
A high speed connection is considered to be 512Kbps of bandwidth with 128Kbps available.
Modems
Modem Installation tools:
- Control Panel, "Add/Remove Hardware" applet.
- Control Panel, "Phone and Modem Options" applet. Tabs:
- Dialing Rules -

Network and Dial-up Connections
Network and dial-up connections are created and configured from the "Network and Dial-up Connections" folder which is accessible from the "Start", "Settings" menu. It us used to create:
- Internet connections - Internet connection sharing is done so other users on the network can share a connection to the internet. Internet connection sharing causes the computer to become a DHCP server, DNS proxy server and change the IP address of the computer to 192.168.0.1.
- Connections to remote access servers
- Direct connections to other computers
- Set up a computer to allow incoming connections
- Create VPN connections
Dial-up Connection Properties
Dial-up connections can be set by clicking on the connection in the "Dial-up Connections" folder. It is used to install network clients and services. Tabs include:
- General - Select the modem or device to use for the connection. Set the phone number and dialing rules. The configure button dialog box includes setting modem maximum speed, protocol, hardware flow control to be set, modem error control to be enabled, modem comptession to be enabled, an initialization script to be run, and the modem speaker to be enabled.
- Options - Can set to display progress of connection, prompt for name and password, include Windows logon domain, prompt for phone number. Cal also set redialing options including the number of redial attempts, time between attempts, and idle time before hanging up. Can configure X.25 settings for connections to X.25 networks. The Windows logon domain option is for the case when there are several Windows 2000 domains on the network being connected to.
- Security
- Networking
- Sharing - Allows the sharing of internet connections by several computers at one time through the computer being configured. On demand dialing can also be enabled.
Windows 2000 Supported Network Protocols
Protocols installed on Windows 2000 systems are normally available to all connections. Protocols are installed and configured from the "Network and Dial-up Connections" folder.
- TCP/IP
- NetBEUI
- NWLink IPX/SPX - Frame types are Ethernet_II, Ethernet SNAP, Ethernet 802.3 (older), and Ethernet 802.2 (newer). May need to configure to use both 802.2.and 802.3.
- AppleTalk - Only available for incoming and local area connections.
- DLC - For connections with older Hewlett Packard printers. This is only available for local area connections.
- Network Monitor Driver
Several transport protocols listed above may be bound to any number of clients or services. This is called binding. Also the order in which a specific transport protocol is used when making a new connection may be set. This means that the connection may be attempted with one protocol, then if that fails, the next protocol is tried. The order is set for connections on a local area connection on the computer. The settings of the bindings is setting the order in which clients are tried when making the connections. Some of these clients include "Client for Microsoft Networks" and "Client Service for NetWare". These are set in the "Network and Dial-up Connections" folder by selecting "Advanced", and "Advanced Settings".

Configuring Services
The Computer Management MMC is used to configure network services. This is done by right clicking "My Computer", selecting "Manage", click the + next to "Services and Applications", and highlight "Services". This starts the Services tool. At this point services can be managed by right clicking on them. They can be stopped, started, paused, resumed, and restarted. Services can be set to have one of the following start up status':
- Automatic - The service starts when the system boots.
- Manual - An application can start the service.
- Disabled - The service can not be started by an application.
A service can be configured to use a particular account when logging onto the system. Service dependencies can be checked.
When a service fails, there are several options that can be set for recovery:
- Take no action
- Restart the service
- Run a file
- Reboot the computer
